Personal profile


Dr. Shan Lou is employed as a senior Research Follow working within the Surface Metrology Group (SMG) of Centre for Precision Technologies (CPT) and ERSRC Future Metrology Hub from 2013. He is currently carrying out research work in the field of geometrical measurement and evaluation for precision engineering.

Shan received his BEng and MEng at Central South University (China) in 2002 and 2006 respectively. He then started his professional career in precision metrology at Hexagon Metrology, a leading global company for metrology industry. He worked as a R&D engineer for the company’s primary product, PC-DMIS. In 2010, Shan moved to University of Huddersfield to pursue a PhD degree whilst working for Hexagon Metrology on a part-time basis.

Shan is an editorial board member of the journal 'Bio-design and manufacturing', a committee Member of the British Standard Institution (BSI) TDW/4/4/1 (XCT), a participating member of ASTM Committee F42 Additive Manufacturing Technologies, a Chartered Engineer of the Institution of Mechanical Engineers (IMechE), a member of the Institute of Mathematics and its Applications (IMA), and a Fellow of the Higher Education Academy (HEA).

Shan was recently awarded an RCUK Catapult Researchers in Residence (RiR) Fellowship. Sponsored by the RiR fellowship, he is working with the Manufacture Technology Centre (MTC), one of the most important Catapult centres in the UK, to investigate and develop bespoke measurement and characterisation methods for additive manufacturing (AM) surfaces, with the aim of linking the manufacturing, functioning and metrology of AM products.

Shan is the peer reviewer for a number of engineering and scientific journals, such as Measurement Science and Technology, Measurement, Precision Engineering, Surface Topography: Metrology and Properties, IEEE Transactions on Image Processing, Optical Express, Assembly Automation. He was also an organising committee members and a session chair of ASPE Summer Topic Meeting – Advancing Precision in Additive Manufacturing 2018, an organising committee member of the 4th Dimensional X-ray Computed Tomography conference, a session chair of the 20th and 25th International Conference on Automation and Computing.

Outside the work Shan enjoys playing badminton and is the faithful fan of FC Internazionale Milano.

Research Expertise and Interests

His research interest is precision geometrical metrology, including surface metrology in microscale and nanoscale and dimensional metrology in macroscale, particularly investigation and development of mathematical principles and algorithms involved with the measurement and evaluation of geometrical elements (such as surface texture, topography and form) for state-of-the-art high-precision products within the high-added value manufacture, especially components with freeform surface and structured surface. The aim is to build a toolbox for the analysis, evaluation and characterisation of geometrical elements using fast, stable and reliable computational algorithms.

He is currently focusing on metrology for additive manufacturing and X-ray computed tomography (XCT) metrology, taking the collaboration of the National Physical Laboratory (NPL) and the Manufacturing Technology Centre (MTC).
